MICHAEL DALLENIBACI-I, OF RIIDGWAY, PENNSYLVANIA.

SAW-GAGE.

To all whom itmay concern:

Be it known that I, MICHAEL DALLENBACH, a citizen of the United States,residing at Ridgway, in the county of Elk and State of Pennsylvania,have invented certain new and useful Improvements in Saw-Gages, of whichthe following is a specification, reference beinghad to the accompanyingdrawings.

This invention relates to new and useful improvements in saw gages andmore particularly to a raker gage for cross cut saws and has for its object to provide a gage of this character which can be easily and quicklyclamped to a saw so that the raker teeth can be leasily set and filed orsharpened into uniformity.

Another object of the invention is to provide a device of this characterwhich will possess advantages in points of efficiency and durability, isinexpensive of manufacture and at the same time is simple inconstruc-tion and operation.

With the above and other objects in view, the invention consists in thenovel features of construction and the combination and arrangement ofparts hereinafter fully described, pointed out in the claims and shownin the accompanying drawings, in which- Figure l is a side elevation ofmy improved gage showing the same applied to a saw; Fig. 2 is a sideelevation showing t-he side opposite from that shown in Fig. 1; Fig. 3is a sectional view on the line 3 3 of Fig. 1; Fig. 4 is a detailperspective view of the clamping vise, and Fig. 5 is a longitudinalsectional view.

Referring more particularly to the drawings 1 indicates the body memberhaving the angular plates 2 secured to the rear facethereof and disposedat each end, said plates having their free edges bent upon themselves toform a groove 3 and a plate 4 is disposed between the body and theplates 2. Two resilient sheet metal straps 5 are provided having one endsecured'to the rear face of the body by means of the screws 6,the otherend is bent twice at right angles and disposed over the angular plates 2and then bent slightly inwardly and curved upon itself to form resilientclamping members 7 so thatv the body member can be securely clamped to asaw.

rlhe body 1 is provided with the recess 8 formed in its upper edge andcentrally arranged. A groove 9 is formed in the rear Specification ofLetters Patent.

face of the body and communicating with said recess.

Adjustably mounted in this groove 9 by means of the set screw 10 is theclamping member 11 provided with the jaws 12, each of said jaws having agroove 13 formed in their inner faces adapted to receive the saw# teeth.Secured to the bot-tom of the body and disposed beneath the groove 9 isa plate 14 having the adjusting screw 15 mounted therein and engagingthe lower end of the clamping member to raise or lower the same, saidmember being held in an adjusted position by means of the set screw 10.

An inverted U-shaped bar 15a is provided having each end secured to thestraps 5 by means of the rivets 16, said bar being disposed directlyabove the recess 8; clamping levers 17 are pivotally mounted on saidbar, having their lower ends bent inwardly at right angles as shown at18 to engage the outer face of the jaws 12 and clamp them securely tothe saw teeth. The upper end of one of said levers is bifurcated asshown at 19 and an operating lever 2O is pivotally mounted in saidbifurcation, said lever being provided with a cam 21 adapted to engagethe flat face 22 formed on the upper end of the other of said levers.

It is obvious to those skilled in wood sawing, that in using a cross-cutsaw for cutting soft woods such as hemlock, pine, etc.,

the points of the raker teeth must be longer than when cutting hard woodas the saw willl cut deeper into the wood at every cross pu l.

The gage is placed over the cutting edge of the saw and presseddownwardly until the teeth `engage the plates 4, one of the raker teethbeing fitted into the grooves 13 of the jaws 12. rIhe operating lever 20is actuated so that the cam 21 will engage the flat face 22 and clampthe jaws 12 tightly onto the teeth, the raker jaws are then filed downeven with the jaws 12, thus making them uniform in length. The clampingmember is to be adjusted by means of the screw 15 according to thelength required .of the raker jaws.

While I have shown and described the preferred form of my invention itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacricing 1 any of the novel features ordeparting from the scope thereof as set forth in the appended claims.

Having thus described the invention what is claimed is l. In a device ofthe character described, the combination of a body having clampingmembers adapted to engage over the cutting edge of a saw, an adjustablysecured clamping member carried by said body to engage the raker teeth,and means carried by said body for clamping said second mentioned membersecurely to the teeth.

2. In a device of the character described, the combination of a bodymember, angular plates secured to the rear face of the body member, saidplates having their free ends bent upon themselves to form a groove,plates disposed in said grooves and arranged between the angular platesand theupper edge of the body member, resilient sheet metal strapshaving one end secured to the rear face of the body member and the otherend bent twice at right angles and disposed over said angular plates andthen bent inwardly and curved upon themselves to form spring clampingmembers to clamp the body member to the cutting edge of a saw, anadjustably secured clamping member carried by said body member andadapted to engage the raker teeth, and means carried by said body toclamp the member securely to the saw teeth.

3. In a device of the character described, the combination of a bodyhaving clamping members adapted to clamp said body to the cutting edgeof a saw, said body having a centrally arranged recess formed in itsupper edge and a groove formed in the rear face of the bodycommunicating with said recess, a clamping member adjustably mounted insaid groove, having jaws disposed in said recess, and means carried bysaid body for clamping said jaws securely to the raker teeth of the saw.

4. In a device of the character described, the combination of a bodyhaving clamping members to clamp said body to the cutting edge of a saw,said body having a recess formed in its upper edge and a groove formedin the rear face of the body communicating with said recess, a clampingmember adjustably mounted in said groove, having jaws disposed in saidrecess, a set screw therein to hold said member in an adjusted position,a plateA secured to the bottom of the body and disposed beneath thegroove, an adjusting screw mounted therein and engaging the lower end ofsaid member to adjust the same, and means carried by the body forclamping said jaws to the raker teeth of a saw.

5. In a device of the character described, the combination of a bodyhaving clamping members to clamp said body to the cutting edge of a saw,said body having a recess formed in its upper edge, a clamping memberadjustably secured to said body, having "jaws disposed in said recess,said jaws having grooves formed in their inner faces to receive theraker teeth, an inverted U-shaped bar carried by the body and disposedabove said jaws, and means carried by said bar to engage said jaws andclamp them tightly to the raker teeth.

6. In a device of the character described, the combination of a bodyhaving clamping members to clamp said body to the cutting edge of a saw,said body having a recess formed in its upper edge, a clamping memberadjustably connected to said body having jaws disposed in said recess,said jaws having grooves formed in their inner faces to receive theraker teeth, an .inverted U- shaped bar carried by the body and disposedabove said recess, clamping levers pivoted to said bar, having theirlower ends bent at right angles to engage the outer faces of said jaws,and means for actuating said levers to clamp said jaws tightly to theraker teeth.
